SPECIFICATION forming part` of Letters Patent No.' 283,120, dated August 14, 1883. Application led December 5, 1882. (No model.) l

`To all whomyit may concern.-

Be it known that we, JOHN N. LAU'rH, of Howard, Centre county, State of Pennsylvania, and ORLANDO B. HARDY, 'of the city and Vcounty of San Francisco, State of California, have invented an Improved Safe; and we hereby declare the following to be a full, clear, and exact description thereof.

Our invention relates-to certain improvements in safes and other similar depository structures; and it consists in certain details of construction, as will hereinafter be fully described, and specifically pointed out in the claim.

Referring to the accompanying drawing for amore complete explanation of our invention,

safe depressed intothe chamber within the masonry, the lock, elevating-ram, andvalve.

A is a chamber, which is formed in the earth below the surface, and surrounded by masonry` or other suitable substance of considerable thickness and depth. We prefer to build within this structure chilled-iron plates, so as to make it entirely burglar-proof if the ma sonry should be partly dug away, while the masonry will be sufficient to make itiire-proof. This chamber is sufficiently large to receive the safe B, whichis exactly fitted to it, and may be lowered into it orraised above the sur- In constructing thissafe, it may be made i with, comparatively thin walls, as its protection depends upon the inclosing-chamber A, and by making it in this manner it will oocupy no unnecessary space when elevated for use. It may also have openings or doors upon more than'one side, so that its contents can be easily reached without the necessity of standing room within it, or be without doors at all. The `whole of the structure may be `made of cheap material and workmanship, ex-

This should be made.

cept the top of the safe. thick and heavy, OI;` the best chilled iron and steel, and is also made fire-proof. The joints are made as nearly air and `water tight as pos.-

sible to protect the contents in case of fire, and to prevent the introduction of explosives, so that when the safe has been lowered into the chamber it will be as nearly fire and burglar proof as possible. In order to raise and depress it, any suitable power and mechanism may be employed-as steam, pneumatic, elec tric, screw, or hydraulic force-with suitable mechanism for operating `the same. In the present case we have shown it to `be operated by hydraulic pressure.

C is a ram, which extends down into a cylinder, D, and up to the safe, which it supports, and it may be continued up through the interior to the top as asupporting and strengthening spindle, as shown.

Water under pressure may be admitted to cock F. The Apipe and cock are preferably located within the solid masonry, so as to be combination-lock, which must be adjusted beplaeed close to the cock and at a considerable distance below the surface, so as to be out of direct reach. A stem, G, extends up to the this point by a disk, H.

In order to lock the safe when it is down in the chamber and prevent it from being raised the safe-bottom and actuated by springsJ, so as to enter corresponding sockets in the walls of the chamberwhenthe safe arrives at the bottom; or the bolts may be stationary at the Qbottom and the sockets K xed to the bottom `of the safeto travel with it, as shown in the present case. The bolthas a piston, L, upon it, and works within a chamber, so that it may be forced back by pressure upon the piston.

the cock is opened to supply the ram, and the rst action is to force the bolts back, and thus allow the safe to be free to ascend by the pressure upon the ram. y

A supplemental valve or cock, M, is tted to the pipe, between the cock F and the ram, and this cock is entirely inclosed within the masonry, as it is never to be used, except in case of accident to the main apparatus. The masonry may then be removed until this cock is exposed, and it may be connected. with `a pressure-pipe, so that the ram may be operated and thesafe raised. I )esks or cases for books R. HARDY, l
